[0002] The pressure tank is used in a closed water circulation system and is installed between the water pump and each terminal device. It can not only store water, but also balance the water volume and pressure, which can avoid frequent opening of the safety valve and frequent water replenishment of the automatic water replenishment valve.

[0027] The water outlet 3 is located below the water inlet 2 and has the same diameter as the water inlet 2 . The width of the through hole 15 is the same as the diameter of the water outlet 3 and the water inlet 2 .

[0028] The water inlet 2 , the water outlet 3 and the pressure gauge 11 all pass through the pressure tank body 1 and the corresponding through hole 15 and extend to the inner side of the inner tank 5 .

[0029] A heating wire 16 is fixedly installed inside the heating layer 6, and the insulation layer 7 is made of glass wool.

[0030] A first protrusion 17 extending outward is arranged on the top periphery of the pressure tank body 1 , and a second protrusion 18 matching the first protrusion 17 is arranged on the bottom periphery of the top cover 8 .
